Today, at its first-ever Slack Frontiers user conference in San Francisco, the company shared a few updates on its business — our first look at Slack's performance since the last time it released some of these numbers in January 2017.

Slack now claims:

Over 9 million weekly active users, up from the 6.8 million it reported in January.

Over 6 million daily active users, up from 5 million in January.

50,000 paid teams, with 2 million paid users, up from 38,000 and 1.5 million, respectively. Slack now says it has a toehold in 43% of the Fortune 100.

Annual recurring revenue (ARR) of $200 million, an extrapolation of how much money it will make in any given 12 months based on its current performance. That's up from the $150 million ARR it reported earlier this year.

Slack also announced Shared Channels, a new feature to let users operate chat rooms that can be populated with internal staff and outside guests. Companies like fashion brand Everlane are using it to bring its shipping contractors closer into the process, says Slack. Also, Slack is now available in French, German, and Spanish, with Japanese coming soon, to meet what it says is large international demand.

Meanwhile, the last week has seen both Microsoft and $8 billion Atlassian draw their respective lines in the sand in these chat wars with Slack.

Coming into the Slack Frontiers event, though, the $5 billion startup doesn't seem worried. Instead, Slack sees itself as the leaders in the work chat space, and these updates "extend our lead," VP of Product April Underwood tells Business Insider.

"We've known for some time that eventually everyone will be using Slack or something like it, so the new products on the market further support that conviction," says Underwood. "We build Slack to meet teams where they are - it's highly flexible and configurable to meet the unique needs of any organization. "
